tion as it is acted upon in the forming-die. Fig. 7 shows the button-die completed, but detached from the button. Fig. 8 shows the same properly inserted in a button, and Fig. 5 9 shows the completed button attached to cloth or fabric.

Referring to the drawings, Fig. 1 shows a circular blank or disk made of any desired suitable size, the latter of or dimension of the finished button-die to be formed there- By means of proper forming-dies this blank is drawn or shaped as shown in Figs.

2 and 3, it being possible, however, as I have found in practice, to dispense with that step of the process for forming the die of the shape as shown in Fig. 2 and to form it of the shape shown in Fig. 3 directly from the blank in one operation. The button-dieAafter assuming the shape as shown in Fig. 3 is then inserted To all whom, it may concern: I

Be it known that I, FRANKLIN G. N EUBERT, a citizen of the United States, and a resident of Waterbury, in the county of New Haven cloth or fabric by means of a metal tack or fastener. This style or character of button is usually constructed with a contained die so placed or situated in the button as to overturn or upset the piercing end of the tack or fastener, said curled or upset end more or less filling the chamber of the die. I have found in practice, however, that in many instances the metal of the upset end of the tack or rivet is not sufficient to completely fill the die, the consequence being that the tack or fastener has more or less play therein and will therefore not withstand the same amount of strain as when the die is completely filled and the tack or fastener held of the button-die A, it is crowded'or forced downwardly within said die B, the effect beto form a shoulder a on the button-die instance, by filling the die with soft metal, paper, or other material, shot within the die, dsc.with more or less advantage.

My invention consists in dispensing with such-material or materials,

as shown at b, Fig. 6, which operation continues until the metal assumes the shape as shown in Fig. 7that is, until the portion Z) is curled and enlarged to'such an extent as to leave but a comparatively small opening 0 and a small space or chamber 0 within the die A. The complete button-die is then inthe depressed centerD of a but- 0 ton E, said button having an opening in the bottom thereof for the entrance of a tack or fastener.

assembling the several independent parts, by

die itself and in such a way that the strainimposed upon the button Wlll be exerted upon the thickened portion of the metal.

lVith these and other ends in View the invention consists in certain novel features of construction, as will be hereinafter fully described, and pointed out in the claims. struck outwardly at several points, causing In the accompanying drawings, Figure 1 is a View of a blank from which the die is formed. Fig. 2 shows the first step in the formation of the die, and Fig. 3 the second step. Fig. 4 shows the partially-formed button-die located within a forming-die. Figs. 5 and 6 show the die in its center of the button and prevent its becoming disengaged therefrom.

To secure the completed button to the cloth or fabric, the tack or fastener F is forced I00 through the fabric G and through the opening in the bottom of the button into the die A,

several stages of forma- 1. Abutton containing adie, thelower edge of which is curled inwardly upon itself, thereby partially filling said die with the metal of which the latter is made, and forming a contracted chamber for the upset end of a tack or fastener, substantially as described.

2. A button containing a die, the lower edge of which is curled inwardly upon itself and thickened, thereby partially filling said die and forming a contracted chamber for the upset end of the tack or fastener.

3. A button constructed with a depressed center, and a die located in said center, and having its lower edge curled inwardly upon it self and thickened, thereby partially filling said die and forming a contracted chamber for the upset end of a tack or fastener, substantially as described.

4c. A button constructed with a die located therein having its lower edge curled and thickened, and provided on its outer side with a shoulder a, substantially as described.

rhereupon the piercing end of said fastener s curled or upset, practically filling the space vithin the die, said curled or upset end restng upon the thickened portion 1) of the die A, bus forming, as I have found in practice, a )ut-ton capable of withstanding a far greater strain than when the die A has simply the bottom thereof bentinwardly to rest flat upon the bottom of the button, as has hereinbefore been done.

13y thus forming a die with a bent or curled and thickened lower portion to partially fill the space within the die a filler in the form of paper or lead shot is entirely dispensed with, and as the button is formed of two parts only the cost and labor of assembling the same are much smaller than where an independent shot or filler is employed.

I am aware that buttons have been constructed comprising a single-piece anvil the lower edge of which is inturned and upturn ed, said inturned edge forming an anchorage for the clenched or upset point of the tack, and hence I make no claim to such, my invention comprising a die having its lower edge curled inwardly and upon itself, as shown in Figs. 7, S, and 9 of the drawings.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

Haven and State of Connecticut, this 17th day of August, A. D. 1.897.
